Some customers may comment on a malfunction indicator lamp illuminated.

During diagnosis, a technician may find DTC P0299, P2227, or P0300 set/stored.

This condition may be caused by a moisture build up inside the charge air cooler. Long drives through rainy conditions and/or high humidity conditions (heavy fog) can cause moisture to collect in the charge air cooler.

A heavy acceleration can draw moisture into the engine causing DTC P0300. In cold temperatures, ambient and PCV moisture can freeze in the charge air cooler, restricting flow, and causing DTC P0299 and/or P2227.

Perform a smoke leak test of the charge air cooler, then follow the repair steps in the appropriate Service Procedure below, depending on the build date and vehicle outside temperature experience.

Note: Deadener material covering is only to be used in northern states or provinces where temperatures are consistently 20?F/-7?C or less.

Service Procedure Equinox, Terrain

Important: For the 2.0L engine ONLY, remove the boost sensor from the intake charge pipe to the throttle body and wipe with a clean rag to remove residual moisture.

1. Perform a smoke leak test of the charge air cooler.

Bulletin No.: 18-NA-020

? If a leak is determined, replace the charge air cooler with the newly designed part. Refer to Charge Air Cooler Replacement in SI.

? If there is NO leak, but a P0300, P0299 and/or P2227 are present, AND the vehicle was built ON or BEFORE March 1,2018, then replace the charge air cooler with the newly designed part. Refer to Charge Air Cooler Replacement in SI.

Important: If the charge air cooler is freezing, and the temperature is NOT going below 20?F/-7?C, install grill covers.

Important: Remove grill covers when the outside temperature is consistently above 40?F/4?C.

Important: The grille cover MUST be removed before towing a trailer of any size. Failure to do will decrease the transmission cooling efficiency and possibly cause damage to the drivetrain.

If the charge air cooler is icing in colder weather conditions, even after using the grill covers, OR the temperature is expected to be consistently below 20?F/-7?C, install 2 pieces of outer panel body deadener P/N 25757810, over the top of the Charge Air Cooler and secure them using zip ties to help prevent icing, following the additional steps listed below.

Important: Grill covers cannot be used when the Charge Air Cooler is covered with the deadener material.
